Abstract

Video quality can be improved by selective duplication of the important video data. This paper proposes a simple and novel scheme to exploit the space occupancy of bi-directionally predicted slices for duplication of selected information in order to improve the video quality. The idea of data duplication is not new, however the selection of the data for duplication and its placement within the transmitted data can have profound effects on performance. The novelty of the proposed schemes is that the duplicated data does not bring additional payload. It is shown that sufficient space exists within video data to accommodate duplication of important data without increasing overall size of video data. The amount of duplicated data can also be tailored to suit specific transmission scenario. The results show significant gains in video quality with the proposed duplication schemes.
